Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The draft concerns a cap with an outflow hole.

[0002]

[Prior art]

 A cap is widely used in which a cap with an outflow hole is formed by a cap body having the outflow hole and an auxiliary cap attached to the cap body by opening and closing the outflow hole via a so-called three-point hinge.

[0003]

[Problems to be solved by the device]

 In the above conventional cap, since the auxiliary cap is elastically inverted, the opening and closing of the outflow hole can be ensured, but since the auxiliary cap is formed almost in the same manner as a normal cap, it can be used as a general cap. On the other hand, there are drawbacks that a large amount of molding material is required and the structure is relatively complicated, resulting in high cost.

According to the present invention, the central portion of the top wall of the cap is formed as an elastic inversion portion with a lever, the outflow hole provided in the inversion portion is opened when the inversion portion is raised by lever operation, and the lever is outflowed when the inversion portion is depressed. The holes are closed so that the outflow holes can be opened and closed with a simple structure.

[0005]

[Means for Solving the Problems]

 The outer peripheral portion of the top wall that hangs the peripheral wall 2 for fitting the neck portion of the container body is a thick-walled flange portion 3, and the central portion of the top wall surrounded by the flange portion is between the front and rear portions of the inner peripheral edge of the flange portion. A refraction plate 7 erected in a V shape through the first and second hinges 5 and 6, and elasticity that descends from both left and right sides of the refraction plate to both left and right edges of the inner periphery of the flange-shaped portion at approximately the same inclination angle. The refracting plate is closed by the thin plates 8 and 8, and the tip of the short plate 9 and the long plate 10 are connected to each other through the third hinge 11 to form the elastically reversible ridge 4. The outflow hole 12 is formed in the short plate 9, and the lever 13 which is longer than the short plate 9 from the tip of the long plate 10 and elastically inverts the raised portion 4 downward is used. The lever 13 protruded at an angle where the side surface could be sealed.

[0006]

[Action]

 In the state shown in FIGS. 1 and 3, the outflow hole 12 formed in the short plate 9 opens. When the tip of the lever 13 is pushed downward to the right in FIG. 1 from the illustrated state, the refraction plate 7 and the elastic thin plates 8 and 8 are elastically inverted as shown in FIG. 2, and at this time, the lever 13 seals the outflow hole 12. . When the tip of the lever is pushed up to the upper left in this state from this state, the outflow hole 12 is opened again as shown in FIG.

[0007]

【Example】

 The cap 1 is integrally formed of a synthetic resin material having excellent flexing and stretching resistance, and has a thick flange-like portion 3 on the outer peripheral portion of the top wall that hangs down the peripheral wall 2 that can be fitted to the outer surface of the neck of the container body. The central portion of the top wall surrounded by the flange-like portion is a raised portion 4 with a lever that can be elastically inverted in the vertical direction. The raised portion is a V-shape, and a refraction plate 7 is installed between the front and rear portions of the inner periphery of the flange-shaped portion via the first and second hinges 5 and 6, and the left and right sides of the refraction plate are disposed on the inner periphery of the flange-shaped portion. It is composed of elastic thin plates 8 and 8 which are slanted down to the left and right sides, and the refraction plate is formed by connecting a short plate 9 and a long plate 10 through a third hinge 11. Further, an outflow hole 12 is formed in the middle portion of the short plate 9 and a sealing ridge is formed around the outer peripheral edge of the outflow hole 12. The short plate 9 is a relatively thick rigid plate, and the long plate 10 is elastically deformable. A lever 13 is projected from the end of the long plate 10 on the short plate side. The lever is provided so that the ridge 4 is elastically inverted downward as shown in FIG. 2 by pushing the lever tip downward to the right from the state shown in FIG. 1, and at this time, the side surface of the lever 13 is an outlet hole. Seal 12 and project it from the end of long plate 10 at an angle. The elastic thin plates 8 and 8 and the short plate 9 described above are tilted at approximately the same angle. However, when this is done, a ridge line is formed in the elastic thin plate part between the long plate side part and the short plate side part. Since the ridge line has a rib function and makes elastic deformation for elastic reversal difficult, as shown in FIG. The ridgelines are prevented by adjusting the inclination angles of the elastic thin plates 8 and 8 in the flange-shaped portions 14 and 14 so that the inner peripheral edges thereof are arcuate. Reference numeral 2a is a seal tube fitted to the inner surface of the neck portion of the container body, and is hung from the inner peripheral portion of the flange portion 3 described above.

[0008]

[Effect of device]

 The present invention is configured as described above, and the outer peripheral portion of the top wall is a thick-walled flange-shaped portion 3, and the central portion of the top wall surrounded by the flange-shaped portion is placed between the front and rear portions of the inner peripheral edge of the flange-shaped portion. 2 a refraction plate 7 erected in a V shape through the flanges 5 and 6, and elastic thin plates 8 and 8 descending from both the left and right sides of the refraction plate to the left and right edges of the inner circumference of the flange portion at approximately the same inclination angle The distal end of the short plate 9 and the long plate 10 are connected to each other via the third hinge 11 to form the elastically reversible raised portion 4, and the lever 13 is projected from the end of the long plate 10. Therefore, by using the lever, it is possible to easily perform the elastic reversal of the raised portion 4, the outflow hole 12 is bored in the short plate 9, and the protruding angle of the lever 13 is set to the raised portion 4. Since the side surface of the lever is provided to seal the outflow hole 12 when is elastically inverted downward, The lever 13 is an operation plate for elastically reversing the raised portion 4 and also serves as a cover plate for opening and closing the outlet hole, which simplifies the structure of the cap and further shortens the length of the lever 13. Since the length of the plate 9 is larger than that of the plate 9, when the ridge 4 is elastically inverted downward, the tip of the lever 13 projects upward from the flange 3 as shown in FIG. This facilitates the elastic reversal operation in the rising direction of the ridge using the.
